Matt Harvey’s been slammed for enjoying the offseason, with one sports blogger writing after he was seen at a Golden Globes party, “In November the playboy was out on the town after the Mets season ended. Two months later, and he doesn’t appear to have gone home yet.”

But although sources tell Page Six the playboy pitcher was in Aspen, Colo., for the holidays, where he hooked up with a leggy brunette, others insist he’s focused on training.

“They were into each other. They were really close and making out,” said a source.

But a pal countered, “He definitely wasn’t making out with anyone in Aspen. He was there with friends. He’s totally single and just focusing on getting in better shape and having a great year.”

Harvey has since been in LA, training at Boras Sports Training Institute for the month.

“He knows training and getting in shape is priority right now,” said the confidante. “He’s getting his ass back in shape to train for baseball. He’s all about baseball. He’s not even thinking about extracurricular activities. He got so close to winning the World Series, he wants a second chance. He really wants it bad.”

Harvey did dodge most of the parties over Golden Globes weekend including the W magazine fête, which was attended by rumored past fling Victoria’s Secret model Devon Windsor.

But he did attend an InStyle magazine soiree with another brunette, spies said, who we’re told is “just a friend.” He split with girlfriend Ania Cywinska (also a model) in October.
